RD 10-249-98 PDF

Full title and description

RD 10-249-98 — Нормы расчёта на прочность стационарных котлов и трубопроводов пара и горячей воды (Standards for Strength Analysis of Stationary Boilers and Steam and Hot Water Piping). The document contains rules and calculation methods for strength, wall thickness, allowable stresses and resource allowances for stationary steam boilers, steam and hot‑water piping and associated vessels connected to boiler systems.

Abstract

RD 10-249-98 establishes normative methods for strength calculations of stationary boilers and steam and hot‑water pipelines: selection of design pressure and temperature, determination of wall thickness and additions, allowable stresses, methods for calculating cylindrical drums, collectors, heat‑exchange tubes and fittings, and provisions for cyclic (low‑cycle) fatigue and brittle fracture resistance where applicable. The document was approved by Gosgortekhnadzor (the state supervisory authority) in 1998 and includes Amendment No.1 (RDI 10‑413(249)‑01) of 2001.

Scope

Applies to stationary steam boilers and steam piping with working pressure above 0.07 MPa, and to hot‑water (water‑heating) boilers and pipelines with water temperatures above 115 °C. Covers boilers with furnaces, waste‑heat boilers, industrial process boilers, integrated and separate superheaters and economizers, downcomer and connecting pipes within the boiler, and other steam and hot‑water pipelines and vessels connected to the boiler circuit (separators, coolers, etc.). The Norms may also be used for strength calculations of energy‑engineering vessels and valve bodies of thermal power plants where appropriate.

Key topics and requirements

• Definition of design (calculation) pressure and temperature and selection of appropriate design values.
• Determination of required wall thicknesses and application of material‑dependent thickness additions and margins (tables of additions such as С21 and rules for various diameters and materials).
• Allowable stresses and material strength parameters for carbon, low‑alloy and austenitic steels at operating and design temperatures.
• Methods for calculating cylindrical drums, collectors, tubes of heating surfaces, conical transitions, domed and flat heads, flanges and fittings under internal pressure and combined loads.
• Procedures for assessing cyclic (low‑cycle) fatigue, creep and brittle fracture considerations in high‑temperature components.
• Rules for evaluating piping elements, welded joints, and specific provisions for heated/unheated components and special fittings (elbows, tees, reducers, etc.).
• Guidance on exceptional load cases (e.g., emergency depressurization, thermal shocks) and required safety checks for membrane structures and other critical components.

Typical use and users

Primary users are design engineers, strength analysts, boiler manufacturers, power‑plant engineering organizations, inspection and supervisory authorities (technical safety and regulatory bodies), and specialists performing lifetime and fatigue assessments of boiler components and steam/hot‑water piping. The document is used during design, strength verification, modification, repair justification and regulatory compliance checks for industrial and power boilers in Russia and organizations applying Russian normative practice.

Related standards

RD 10‑249‑98 replaces or updates a number of earlier industry normative documents for stationary boilers and piping (examples include RD 108.031.115‑88 and several OST/RTM predecessors). It is used alongside GOST standards for stationary boilers and strength analysis (for example later GOST publications that reproduce or update sections of RD), and with the Technical Regulation of the Customs Union / TR CU requirements on pressure equipment where applicable. Implementing documents and clarifications from supervisory authorities (Rostekhnadzor/Gosgortekhnadzor) provide interpretive guidance.
